  1. * Too few samples to calculate sensitivity
  2. † Included samples were negative by microscopy and PCR, but positive by the OptiMAL and/or the SDFK60
  3. ‡ Incorrect diagnosis consisted of two samples diagnosed as Plasmodium negative and one sample diagnosed as a single P. falciparum or a mixed infection of P. falciparum with one or more of the non-falciparum species.
